so i'm thinking A because of my pKa numbers but it also might be B?!?

[catsarecute02]

i might be getting my pKa numbers wrong...

I think that your pK_a for Ph-NH₃⁺ is off a bit.  I am having a difficult time reading your pK_a for thiol groups.  In my experience they often fall in the range 8-10.

[catsarecute02]

my thiol group has 10.6

but would the answer be A or B?

[Babcock_Hall]

What is the pK_a of acetone?  If you know this value, then you should be fine.

[catsarecute02]

19.3 and i put 19 so my answer of A is correct?

[Babcock_Hall]

As far as I can tell, A has the correct order, but your pK_a value for the anilinium ion is wrong by a good six orders of magnitude.
